Abstract: A sheet supply system, for use in supplying overlapped sheets to an interfolder, includes a bed roll on which a web is cut into successive sheets. The sheets are supplied to a sheet supply passage leading to retard rolls, which overlap the sheets within the supply passage. The trailing portion of each downstream sheet bulges outwardly as the sheet is supplied to the supply passage. An air tube directs pressurized air into a volume within which the bulge in the downstream sheet is formed. The pressurized air prevents the leading portion of the upstream sheet from being drawn outwardly along with the trailing area of the downstream sheet, by counteracting a vacuum that results from outward movement of the trailing portion of the downstream sheet after it is released from the bed roll.

Abstract: A system for building a database that stores information representative of the organizational structure of a community of users of a computer network is disclosed. The system uses an online computer applications service that facilitates the initiation and completion of transactions between users in the community. Initially, a first user from the community registers on the computer applications service and information representative of the first user is stored in the database. Next, a first transaction record is created in the database from information inputted by the first registered user. The first transaction record includes at least one field representing an identity of a first unregistered user in the community, a field representing a role of the first registered user in the first transaction, and a field representing a role of the first unregistered user in the first transaction.
